INTRODUCTION

This article contains information about the restrictions and limitations that apply when you use OneDrive for Business (onedrive.exe) or OneDrive for Business for Mac OS X to sync SharePoint Online OneDrive for Business libraries to your computer.

Note To determine which OneDrive sync client you're using, see the following Microsoft website:

If you're looking for restrictions and limitations that apply to the earlier version of OneDrive for Business (groove.exe), see the following Microsoft Knowledge Base article:

MORE INFORMATION

Supported libraries

OneDrive for Business can sync both OneDrive for Business libraries as well as SharePoint Online document libraries from team sites. For more information about this functionality and how to set up team site sync using OneDrive for Business, see the following Microsoft website:

This folder name isn't supported when the folder is at the root level for a library

Number of items that can be synced

Although SharePoint Online can store 30 million documents per library, for optimum performance we recommend syncing no more than 300,000 files across all document libraries. Additionally, the same performance issues can occur if you have 300,000 items or more across all libraries you are syncing, even if you are not syncing all items in those libraries.

This is a suggested limit that is reliant on the length of file paths and hardware specifications of the device running the OneDrive app. Many customers are able to sync more files without experiencing any issues.

Note: If you are uploading, downloading, or moving a large number of files at once, you may need to wait an extended period of time before the sync process can complete. The client showing “syncing” icon or displaying "proecssing changes" during this period is not necessarily an indication of a problem. You can always click the OneDrive taskbar icon to see the status of content that is in the process of syncing. To help reduce sync times, we recommend reviewing and possibly modifying your bandwidth settings before starting your upload or download. You can also read how to Choose which OneDrive folders to sync to your computer.

There are other limits on viewing a document library using the web that may affect how you structure your files in OneDrive.

We encourage feedback as we are always working to optimize OneDrive to better handle libraries with a large number of files.

Size limit for syncing files

There's a 15-gigabyte (GB) file size limit for each file that's uploaded to the OneDrive for Business library.

Character limit for files and folders

In SharePoint Online, file name paths can have up to 400 characters. The limit may be less than 400 characters in some scenarios, especially if you have a very long URL path for the library. (Note: Some older Office version may have a lower limit, see KB 326039 for details)

Sync folder location set to a network drive

You can't add a network or mapped drive as your OneDrive sync location.

Shared with Me

You can't synchronize the Shared with Me view grouping of files from a OneDrive for Business site.

Syncing with an external or guest account

Synchronizing content using an external or guest user is currently not supported by OneDrive

Libraries with Information Rights Management enabled

Libraries can be synchronized as read/write with OneDrive build 17.3.7294.0108 or later.

Syncing IRM-protected libraries isn't yet supported for Mac OS X.

Elevated privileges

OneDrive can’t be run with elevated privileges.

Differential sync

Differential sync is only possible for Microsoft Office files in the new file format, .docx, .pptx, .xlsx. OneNote files are not included.

This is part Office Integration and requires:

Office 2016 Click To Run (version 16.0.6741.2027 or higher). You must also have OneDrive (version 17.3.6386.0412 or higher).

The onedrive.exe OneDrive for business sync client doesn’t support synchronization of SharePoint on-premises data. If you want to sync from SharePoint on-premises environments, you should use the previous OneDrive for Business application (groove.exe).

Symbolic or soft links

OneDrive doesn't support symbolic links where the Link and Target are both located in the same library location.

Having two different paths to the same set of files in the target folder may lead to performance and stability issues. Symbolic links provide an alternate path to an existing folder and are typically created using the mklink command.

OneNote notebooks

Because OneNote notebooks have their own sync mechanism, they shouldn't be synced by the OneDrive for Business sync client. Instead, you should save your OneNote files through OneNote or the web to OneDrive. OneDrive will create a stub file in your sync folder, depending where you saved the OneNote file.

Open files can't be synced

A file that’s currently opened by an application can't be synced by OneDrive for Business. To sync the file, close any application where the file is currently being used, and then sync the file.

This limitation doesn’t apply to co-authoring scenarios when you use the Microsoft Office applications described in the "Office integration" section.

Lookup columns in a library

The OneDrive for Business library can't exceed the lookup column threshold. For more information, go to the following Microsoft Knowledge Base article:

2927386 "We couldn’t sync this library" error when you use the OneDrive for Business sync client

Office integration

The OneDrive sync client for Windows supports co-authoring and in-app sharing when you use Office 2016 Click 2 Run (version 16.0.6741.2027 or higher). You must also have OneDrive (version 17.3.6386.0412 or higher).

The OneDrive sync client for Windows supports co-authoring and in-app sharing when you use Office 2016 MSI and have the following update installed:

Windows specific restrictions and limitations

Windows Explorer displays the first 35 characters of a site library’s name and site name combination for a library that you have synchronized. This doesn’t affect the ability to sync these items within the limits that are described in this article.

Roaming, Mandatory and Temporary Windows profiles aren't supported. The OneDrive for Business sync app only supports users who can write to OneDrive for Business application directories.

Additionally, the OneDrive for Business sync app isn’t supported for client sessions that are hosted on Windows 2008 Terminal Services or Windows 2012 Remote Desktop Services (RDS). This includes both persistent and non-persistent Virtual Desktop Infrastructure (VDI).

For the OneDrive for Business sync app to work as designed, the following requirements must be met:

The application must be installed on the local computer.

The user must be able to write to the user profile.

Data that's written to the user profile must be saved to the local hard disk and be available without a network connection.

OneDrive Files On-Demand is only supported on Windows 10 Fall Creators Update and later versions.

Microsoft Support and Recovery Assistant for Office 365
